Nscale Taps Fidji Simo for Board Role as IPO Looms

Nscale, the UK startup building advanced AI data centers, has added Fidji Simo—former exec at OpenAI, Meta, and Instacart—to its board ahead of a planned IPO likely this fall.

Who Fidji Simo Brings to the Table

Simo most recently served as CEO of AGI Deployment at OpenAI, a role akin to the company’s second-in-command. She stepped down in July, citing health reasons, yet continues to advise OpenAI on a part-time basis. Before that, she was CEO and chair of Instacart, guiding it through its 2023 IPO. Her earlier career includes over a decade at Meta, including leading its Facebook app. She also sits on Shopify’s board.

Nscale’s Board, Ambitions & Financial Stakes

Her addition joins board members Sheryl Sandberg, Susan Decker, and Nick Clegg. According to Nscale’s CEO Josh Payne, Simo was selected for her rare experience in scaling platforms to billions of users—a capability directly aligned with Nscale’s mission of building infrastructure that supports massive AI workloads.

The company’s growth has been swift: founded just two years ago, Nscale designs, builds, and runs AI-focused data centers. Demand for AI infrastructure has driven up its valuation. It’s reportedly preparing to raise as much as $3.5 billion in funding ahead of its IPO.

Why This Move Matters

Nscale is positioning itself for the big leagues. With technology giants and hyperscalers investing heavily in AI infrastructure, startups in this category are under pressure not just to build capacity, but to prove they can scale, manage finances, meet regulatory standards, and operate at enterprise-grade levels. Bringing on a leader like Simo helps Nscale address those demands more convincingly.

This development also signals investor confidence—adding a high-profile executive with both product scaling and go-public experience usually reassures stakeholders ahead of listing.

What to watch next: whether Nscale’s funding round closes at the rumored amount, how it plans to deploy its capital (build new centers vs. expand existing ones), and how it stacks up against other infrastructure plays in AI. If it succeeds, it could set a blueprint for how infrastructure-focused startups navigate public markets.
